LAKE TOWNSHIP, MI -- A 4-year-old Illinois boy has lost his fight for life after being pulled from Lake Michigan on Aug. 1 at Warren Dunes State Park in Berrien County.

Matthew Ramirez, of Palatine, Ill., died early on the morning of Saturday, Aug. 5, at Bronson Methodist Hospital as a result of his injuries.

Berrien County Sheriff's deputies reported the death on Tuesday, Aug. 8, in a press release.

The child had been listed in critical condition since being transported to Lakeland Hospital in St. Joseph and then being airlifted to Bronson hospital. Deputies say he was pulled from Lake Michigan by good Samaritans, who spotted him floating and unresponsive in the water.

Those people, who were not identified by police, performed CPR on the child until emergency responders arrived and took over the life-saving efforts. The incident occurred before emergency help was called at 7:45 p.m. on Tuesday, Aug. 1.

"The preliminary investigation shows that the child was visiting Warren Dunes State Park with several family members and several children were playing in the water," deputies reported. "It appears as if some of the family members believed the child had exited the water and returned to the beach area with other family members, while in fact he remained in the water unbeknownst to the family members, until he was discovered in the water by the good Samaritans."

An autopsy was conducted on Saturday and the results are pending, according to deputies. The case is to be forwarded to the Berrien County Prosecutor's Office for review.

The Berrien County Sheriff's Department issued a reminder to parents and others to keep watch over children playing in bodies of water. They stated that swimming skill levels and rip currents can contribute to drowning accidents.
